Given numbers are 863,903,989,416,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 863,903,989,416,161 is 7456237152.
Find LCM of 863,903,989,416,161 with Prime Factorization
| 7 | 863, 903, 989, 416, 161 |
| 23 | 863, 129, 989, 416, 23 |
| 43 | 863, 129, 43, 416, 1 |
| 863, 3, 1, 416, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 43 x 863 x 3 x 1 x 416 x 1 = 7456237152
Therefore, the lowest common multiple of 863,903,989,416,161 is 7456237152.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
863 x 903 x 989 x 416 x 161 = 51619529803296
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
863 : 1, 863
903 : 1, 3, 7, 21, 43, 129, 301, 903
989 : 1, 23, 43, 989
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,903,989,416,161, is 1.
Now, the common factors can be found like this.
863:863
903:3x 7x 43
989:23x 43
416:2x 2x 2x 2x 2x 13
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23x 43 = 6923
Therefore, the value for common factors is 6923.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 51619529803296/(1x6923)
LCM = 51619529803296/6923
LCM = 7456237152
Thus, we can understand that the LCM of 863,903,989,416,161 is 7456237152.
